I have a Cisco 1401 router (from the 1400-series) that is cooled by an extremely noisy "Fonsan DFD0612L" fan. I tried flipping the fan, which lowered the noise level a bit, but hardly noticable. My questions are...
(1) What is the fan cooling? Power supply, chipset, everything?
(2) How much will I decrease the lifespan of my router if I remove it completely? What are the risks? Will I get proper warning or will the device burst into flames?
The router is accessed by two computers, using it for general web surfing via an ADSL line. I have never noticed the router getting hot or even warm from daily use.
Thanks for your time and please post if you want me to elaborate.
I am currently running the router without a fan, so the interesting thing for me is not if it is possible -- but more how long I can expect it to live and whether it will stay cool or burst into flames :-)
I might be able to replace the fan with a quieter one, but is it possible to reduce the noise level so much, that you can live and sleep a few feet from the router?
As for the network part: My DSL provider is based on ATM25 technology and since I need multiple IP capabilites, my choice of routers is very limited -- two to three offers these options to my knowledge.
I am not sure how relevant this is for a hardware discussion forum, but yes; it is business class DSL.
My provider is Zillion (TDC) and the product is Pro@ccess ADSL. I am pretty sure they only offer their services inside Denmark. The modem, router and PC connects via normal RJ-45 cables. The only serial port in use, is PC COMM port <-> CISCO console port -- only used when configuring the router.
